Application filed May 10,

To all whom it may concern:

Be it known that I, JoHN GIOVAGNOLI, a citizen of the United States, and a resident of Flushing, Queens County, have invented a new and useful Improvement in Mortar Spreaders, of which the following is a full, clear, and exact descriptlon.

My invention relates to improvements in motar spreaders, and is adapted for use in laying mortar, cement, or the like on hollow tiles or other articles which are cemented by mortar or other plastic substance so as to lie edge to edge, and with continuous cells or openings passing from one to the other. These hollow tiles and similar articles are'used very extensively, as is well known, in building purposes. and are .laid edge to edge so that the cells of one tile will continue through those of the next, thus making a continuous air channel through them. In laying these things, the mason finds great difficulty because the edges to which the mortar or cement is applied are rather narrow, and it is difficult to place the mortar upon them without spilling a great deal of it into the cells, and also on the outside. This results in a great waste of mortar or cement, and moreover as the tiles are continuous one above the other, the mortar ultimately defeats the purpose of the tile, as the lower tiles will have their cells filled with the falling mortar. F urthermore, skilled masons are expensive laborers, and it requires a good deal of time to lay the tiles or the like accurately. The object of my invention is to produce an extremely simple device which can easily be applied to a tile so as to close the openings therein, and leave a space in which the mortar can be placed so that it will lie evenly on the top edges of the tile without spilling any into the cells.

In carrying out this idea, spreader is placed on the tile so as to cover the openings and leave channels registering with the solid parts of the tile, the mortar is smoothly spread across the top of the tile, filling the channels, it is then scraped off clean with the trowel, and the spreader can then be lifted from the tile leaving the mortar evenly applied to all the solid parts thereof, so that the next tile can be placed thereon easily and with the joint nicely mortared or cemented.

It will be readily seen that such an arthe mortar Specification of Letters Patent.

not used, because he avoids the necessity of carefully applying the to the solid parts of the tile. better understood from th which follows. 7

Reference is to be had. to the accompanymg drawings forming a part of this specificat on, in which similar reference characters lndlcate corresponding parts in all the views.

Figure 1 1s a perspective view showing my mortar spreader applied to the top of a hollow tile, but with the channels unfilled, and

F igure 2 is a longitudinal section through the spreader and tile showing the channels of the spreader filled.

This will be e description tile, as presently described.

he spreader is provided also with covers 13 which are spaced apart on the inner portlon of the spreader so that their tops shall lie in the same plane as the top of the platethe cross walls of the tile. 13 can be braced by thin cross pieces 14 extending from a flange members 13, and they with internal cross braces 15.

It will be seen that the arrangement described makes a channel 17 between the part while the cross channels 18 between the members 13 will be made to register with the cross walls 20 of the tile. Attention is called also to the fact that the flanges 16 and 11 are preferably slightly inclined as shown clearly in Figure 2, so

that after the channels are filled with mortar, the spreader can be easily lifted from the tile without disturbing the mortar which has been placed in the channels.

In practice, assuming the tile to be in its vertical position, the spreader is placed thereon as described, and a quantity of mortar placed on the spreader and smoothed across the same with a trowel, and the channels referred to will be filled with mortar, the surplus being scraped off with a trowel, and none will fall into the cells 21 of the tile. The spreader is then lifted off, leaving the mortar, as stated, on the walls of the tile. Another tile can then be placed in the usual way on the tile to which the mortar has been applied, and the work proceeded with.

It will be noticed 10 affords a convenient hand-grip for handling the device, and it will be evident that the spreader can be made in any size or shape to correspond with the article to which it is to be applied or on which it is to be used, the only essential thing being to have the spreader provided with a flat top surface, with channels to register with the cells of the hollow article to which the mortar is to be applied, and that cover members are provided to span or cover the cells or hollows of said articles.

I have shown the mortar spreader as applied to the conventional tile, but it will be understood that the size and shape of the device can be changed to suit the corresponding dimensions of the article to be mortared or cemented.

Attention is called to the fact that burnt clay products, such as hollow tile, are rough products, and vary greatly in thickness.

that the plate or flange.

Sometimes two blocks will vary a half inch bottom part of the spreader he left plane, without overlapping either side of the block, to the end that the channels in the spreader can be made to register accurately with the solid portions of the tile. It is also essential that the top surface be left perfectly plane, in order that the mason may with one stroke of his trowel, spread the mortar over the top, and fill the various channels.

I claim 1. As an improved article of manufacture, a mortar spreader having longitudinal and transverse channels adapted to register with the walls of a hollow tile or the like, said spreader having a plane top surface, and having the lower edges of the channel walls also in a plane parallel with the top surface, the outer side walls of the spreader being left flat and unobstructed and projecting on all sides beyond the outer channel wall to form handles.

2. A mortar spreader comprising a flat plate of sheet metal having down-turned channels with diverging walls said channels being adapted to register with the partition walls of a hollow tile or the like, the spreader having its top projecting laterally on all sides from the outer channel wall to form handles, a plane flat top surface, and the bottom walls of the channels in a plane parallel withthe top of the spreader, the outer parts or periphery of the spreader being left flat and unobstructed.
